This invention also includes preparation of non toxical salts of amino-alcohols of formula I, such as hydrochlorides, hydrobromides, phosphates, sulfates, oxalates, lactates, tartarates, acetates, citrates, maleates and the like.

The compounds according to the invention comprise one or more asymmetric carbon atoms and can thus exist as optically active isomers, racemics and diastereoisomers. All said different forms are included in the present invention.

Thus if in the general formula I, R₄, R₅ and R₆ comprise no asymmetry centre, one obtains a racemic mixture of enantiomers, said mixture can be resolved by means of well known processes such as for example formation of a salt with an optically active acid and separation of the mixture of diastereoisomer salts through fractional crystallisation, chromatography, distillation. As resolution agent, one uses for example the optically active forms of tartaric, diacetyltartaric, dibenzoyltartaric, ditoluyltartaric, camphorsulfonic, bromocamphorsulfonic, malic and mandelic acids. If in formula I, one or more of R₄, R₅ and R₆ contain an asymmetry element, two or more diastereoisomer mixtures are obtained. Said diastereoisomer mixtures can very easily be separated through fractional crystallisation for example and the racemics can be resolved through already previously cited conventional processes.

It is known that the 1-aryl-2-aminoethanol derivatives have the property to block the β -adrenergic receptors.

It has been found that if the compounds of general formula I always have said property, while being free of sympathicomimetic effects, they are moreover provided with other pharmacological activities which differentiate them from known products.

Thus the products of the invention have a marked peripherical vasodilatator activity which appears at very low doses.

It has also been remarked that said products can induce an oxygen saving at the level of the myocardium.

Due to the fact that the blocking agents of the adrenergic receptors are often administrated in case of deficiency of heart oxygenation (pectoris angina), the association of an activity allowing an increase of the energetic efficiency of the heart with said β -lytic action is of an obvious therapeutical interest.

The products according to the invention are also endowed with an anti-arrhythmic and hypotensive activity. The pharmacological characteristics of said products must allow use thereof in the treatment and prophylaxis of affections of coronary vessels, in the treatment of cardiac arrhythmiac, as peripheral vasodilatator and as anti-hyportensor.

Their blocking activity of β -adrenergic receptors allows an action on metabolic effects of adrenergic amines and more particularly the mobilization of glucose and free fatty acids. Moreover, said compounds show a low toxicity, which allows a long-lasting therapy securely.

This invention also claims pharmaceutical compositions containing, as active ingredient, at least one compound of general formula I and/or a salt thereof with a pharmaceutical excipient. Said compositions are presented so as to be able to be administrated orally, rectally or parenterally.

Thus for example the compositions for oral administration can be liquid or solid and presented as tablets, capsules, granules, powders, syrups or suspensions; such compositions comprise additives and excipients, generally used in galenic pharmacy, inert diluents, desintegration agents, binding agents and lubricating agents, such as lactose, starch, talc, gelatin, stearic acid, silicic acid, magnesium stearate, polyvinylpyrrolidone, calcium phosphate, calcium carbonate and the like.

Such preparations can be made so as to increase the desintegration time and consequently the duration of action of the active principle.

The aqueous suspensions, oily emulsions and solutions are prepared in the presence of sweetening agents, such as dextrose or glycerol, of perfuming agents, such as vanilline for example, and can also contain thickening agents, wetting agents, preservative agents.

The oily emulsions and solutions are prepared in an oil of vegetal or animal origin and can contain emulsifying, perfuming, dispersing, sweetening and anti-oxidizing agents. For parenteral administration, one uses as vehicle sterile water, an aqueous solution of polyvinylpyrrolidone, peanut oil, ethyl oleate and the like. Said injectable aqueous or oily solutions can contain thickening, wetting, dispersing and gelifying agents.

The new compounds according to the invention are prepared according to the general process forming the subject of the present invention and defined as follows:

New amino-alcohols and salts thereof are prepared from a compound having the formula: ##SPC2##

or eventually, according the the value of Q, from a salt of a compound having said formula, wherein R₁, R₂ and R₃ have the meaning given hereinbefore and Q represents one of the following groups. ##EQU1## In said groups, R₄, R₅ and R₆ have also the meaning hereinbefore given while Y represents a --CO-- or --CHOH-- radical and X represents a halogen atom.

This general process can be carried out according to several ways which are substantially determined by the starting product, i.e. by the value of Q in formula II.

Said various modes of preparation are described hereinafter and for easiness are successively defined as processes A to E.

Process A

According to this way to proceed, an α -aminoketone having formula (II), wherein Q represents the group ##EQU2## in which R₁ to R₆ have the meaning given hereinabove is reduced.

This reduction can be made in the usual way, for example by hydrogenation in presence of a catalyst, such as palladium on carbon, nickel Raney or platinum, in the presence of a solvent such as methanol or ethanol, at ordinary or high pressure, or still by action of alkali metal hydrides such as sodium borohydride, in a solvent such as methanol or ethanol, preferably at low temperature, or by action of aluminium and lithium hydride in ether or tetrahydrofuran, preferably at low temperature, or still by action of aluminum alkoxyde, such as aluminium isopropoxide, in a solvent such as isopropanol, the most avantageously at reflux of the latter. It is to be noted that the reduction can eventually be made on a salt of compound II (hydrochloride, oxalate and the like) in case of the preparation of an amino-alcohol salt.

The starting compounds of general formula II, wherein Q has the above meaning are easily obtainable, for example by action of an amine R₅ R₆ NH on a α -halogenoketone in inert solvents, such as ether, benzene, chloroform, dioxan, a lower alcohol such as methanol, ethanol or isopropanol, or also acetonitrile, this in the easiest way at ordinary temperature or in the cold. Said starting compounds can also be obtained by Houben-Hoesch reaction from an aminoalkylnitrile of the type CN-CH(R₄)-- ##EQU3## and from suitably substituted benzene compounds. H.D. Moed Rec. Trav. chim. 71, 933 (1952).

Process B

According to this other mode of preparation, a compound of formula (II) wherein Q represents one of the groups ##EQU4## is reacted with an amine of the type R₅ R₆ NH, formulae in which R₁ to R₆ have the meaning given previously and X represents a halogen atom.

This particular mode of preparation can be more completely represented by the following scheme: ##SPC3##

The reduction of compounds III is made according to conventional processes already described previously; it is known in the literature that one can obtain either compound IV or a mixture of compounds IV and V, and this more particularly when reductions are made by metal hydrides. Each of both said compounds or the mixture can be directly reacted with an amine derivative R₅ R₆ NH. It is also well known in the literature that the action of an amine on a compound of type IV so as to obtain compound I passes through an intermediate epoxide of type V; for practical reasons, it is however sometimes easier to quantitatively form epoxide V by treating product IV with a basic agent such as sodium hydroxide, potassium hydroxide or a sodium alkoxide.

The opening of the epoxide by amine R₅ R₆ NH is made in a solvent such as methanol, ethanol, isopropanol, dioxan, benzene, dimethylformamide, or also without solvent in the presence of an excess of the amine derivative, at a temperature between room temperature and reflux temperature of the selected solvent. The reaction can also avantageously be made under pressure in an autoclave and a condensation agent, such as sodium hydroxide or acetate can be used.

Compounds I can also be obtained by starting from compound IV by action of an amine R₅ R₆ NH in a solvent, such as dioxan, chloroform, ethanol, isopropanol or diglyme, this the most easily at reflux temperature of the selected solvent; this reaction can be carried out in the presence of a product fixing liberated hydrogen halide, for example a mineral base or an excess of the amine used.

Starting products III are the most easily obtained by halogenation of the corresponding ketone, or also by Friedel-Crafts reaction by starting from suitably substituted benzene compound and from acid halide of the type X--CH(R₄)--COX (X = halogen).

An epoxide of type V can be obtained from suitably substituted benzaldehyde by action of dimethylsulfoxonium or dimethylsulfonium methylide. E.J. Corey J. Am. Chem. Soc. 87, 1353 (1956 A.Z. Britten Chem. & Ind. 771 (1968).

Process C

According to this way to proceed, new aminoalcohols of the invention are prepared by transforming a dicarbonyl compound of formula II, wherein Q represents the group

    --CO--CO-- R.sub.4,

r₄ having the meaning given previously, by simultaneous action of an amine R₅ R₆ NH or of an hydroxylamine R₅ R₆ NOH and of a reducing agent, R₁ to R₅ having the meaning given previously, while R₆ represents hydrogen.

The reduction is carried out by catalytic hydrogenation in the presence of platinum or nickel Raney for example and in a solvent, such as methanol or ethanol either at atmospheric pressure or at a higher pressure. Reduction can also be made with an alkali metal hydride, for example sodium borohydride, in a solvent such as methanol, preferably at low temperature.

It is to be noted that reduction can be carried out on bisulfitic derivatives, hydrates or acetals deriving from precited dicarbonyl compound. Said compound is obtained the most easily when R₄ = H, from corresponding acetophenone by action of an oxidation agent, such as selenium dioxide, in a solvent, such as dioxan or water, by action of dimethyl sulfoxide on a α -halogenoacetophenone of the type responding to formula III [N. Kornblum J. Am. Chem. Soc. 79, 6562 (1957) ], also from α -dihalogenoacetophenones [F. Venien C.R. Acad. Sci. 266 1650 (1968) ] or still by means of conventional methods well known in the literature [ Org. Synth. II 511 et 48 109 ].

Process D

According to this other mode of preparation, new amino-alcohols of the invention are obtained by reacting a starting compound of formula III, wherein Q represents the group ##EQU5## Y representing either radical -- CO-- or radical -- CHOH-- and R₄ having the previously mentioned meaning, under reducing conditions, with a carbonyl compound of the kind R₅ R₆ C = O, wherein R₅ represents hydrogen, linear or branched alkyl radical, alkenyl, alkenyl, alkynyl or substituted alkyl radical, and R₈ is a linear or branched alkyl radical or a substituted alkyl radical; R₅ and R₆ can form with ketone function an alicyclic or heterocyclic system; the alkyl radicals substituted in R₅ and R₆ are substituted by amino, alkylamino, hydroxy, phenoxy, substituted phenoxy, phenyl, substituted phenyl and heterocyclic groups.

The reducing alkylation of a starting compound of said type is carried out in the presence of hydrogen and of a hydrogenation catalyst, such as platinum oxide or palladium on carbon in a solvent, such as methanol, ethanol, ethyl acetate or glacial acetic acid, at ordinary pressure and more advantageously at higher pressure, or still with an alkali metal hydride such as sodium borohydride in a solvent, such as methanol, or aluminium and lithium hydride in a solvent, such as ether or tetrahydrofuran; when compound R₅ R₆ C = O is a ketone, one can work without solvent in the presence of an excess of ketone compound.

Said starting compound can be formed in situ from compounds of following types VI and VII: ##SPC4##

Y = co, a = cn, --n₃, = n₂, = noh, y = choh, a = no₂, --cn, --n₃

the α -cyanophenylketones (VI: Y = CO, A = CN) are obtained for example by reaction of suitably substituted benzoyl chloride with a cuprous cyanide [ G. Zolss Sci. Pharm. 32 76 (1964) ], the α -azido and α -diazo alkylketones (VI: Y = CO, A = N₃ and = N₂) are prepared by processes well known in the literature (Houben-Weyl; Methoden der Organischen Chemie "Stickstoff Verbindingen I Vol 10/3); the insonitriketones (VI: Y = CO, A = NOH) are for example obtained from suitably substituted acetophenones (R₄ = H), propiophenones (R₄ = CH₃) and the like, by action of an alkyl nitrite, such as methyl, butyl or amyl nitrite in acid or basic medium; the 1-phenyl-2-nitroalkanols (VI: Y = CHH, A = -- NO₂ ) are for example obtained by reaction of a suitably substituted benzaldehyde with a nitroalkane (nitromethane, nitroethane); the cyanohydrins (VI; Y = CHCH; A = CN) are obtained from a suitably substituted benzaldehyde and from hydrocyanic acid or a salt thereof with an alkali metal; the 1-phenyl-2-azidoalkanols (VI: Y = CHOH; A = N₃) are for example obtained by reaction of an epoxide of type V with sodium azide [ C.A. Vanderwerf J. Am. Chem. Soc. 76 1231 (1954 )]; an oxazolidone of type VII is for example obtained from a compound of the type ##EQU6## by Curtius rearrangement.

The above starting compound can also be obtained from a halogenoketone of type III by action of phthalimide, hexamethylene tetramine or ammoniac, or also from an epoxide of type N by action of ammoniac.

A halide of type R'X can also be used, wherein X represents a halogen and R' represents an alkyl, substituted alkyl, cycloalkyl, alkenyl or alkynyl radical.

Process E

According to this still other embodiment, amino-alcohols of the invention are obtained by reducing a starting compound of formula (II) wherein Q represents the -- CHOH-- CO-- ##EQU7## group, R₅ and R₆ having the meanings given previously.

The reduction of such a starting compound is the most easily carried out by means of an alkali metal hydride, such as lithium aluminium hydride, in a solvent such as diethyl ether or tetrahydrofuran at the cold or more avantageously at the reflux of the selected solvent.

Salts of amino-alcohols can be prepared, according to the invention, as previously mentioned, by the general process hereinbefore described.

Said process includes several variants. Generally, said salts can be prepared by well known methods of said general process, such as for example reaction in equimolecular amount of the amino-alcohol with an acid in a suitable solvent, such as an alcohol for example, then precipitation of the salt by addition of another solvent miscible with the first one acid, in which the salt is insoluble, such as ether for example; or still by neutralisation of an ethereal solution of the acid or base by the base or acid. The acids are either inorganic acids or organic acids. As inorganic acids, preferably hydrochloric, hydrobromic, sulfuric, phosphoric, perchloric acids and the like are used. The organic acids are either carboxylic acids, or sulfonic acids, such as formic, acetic, propionic, glycollic, lactic, citric, ascorbic, fumaric, maleic, pamoic, succinic, tartaric, phenylacetic, benzoic, p-aminobenzoic, anthranilic, p-hydroxybenzoic, salicylic, methanesulfonic, ethanedisulfonic acids and the like.

Another variant of the general process for preparing salts, in the case of Q in formula (II) represents one of the ##EQU8## or ##EQU9## groups, Y and R₄ to R₆ having the meanings given previously, consists of directly making the reduction on a salt of this starting compound, so as to obtain a corresponding salt of an amino-alcohol having formula (I)

Said various variants of the process according to the invention are each hereinafter illustrated by means of relatively detailled preparation examples of a series of compounds said examples being then followed by a Table comprising characteristics of an important group of compounds which are prepared according to said various modes of preparation.

Compounds which, in this Table, do not present an asterisk (*) near their crude forumal were prepared according to at least one of the five variants of the process according to the invention, while compounds presenting an asterisk (*) were only prepared according to at least one of the variants defined hereinbefore as process A, B, E.
